The brackets aren’t set up with that in mind but it could be doable. I don’t really need any more weight than this to be honest.Would you be able to rotate it and carry it with the weights away from the tractor for other jobs if you weren’t carrying the press? There’d be a fair bit of more leverage with it turned 180 degrees.
It can be used on the rear links too for loader work. The tractor came with its own 870kg block too.
Front wheel weights would be a solution too but more effort to put on or remove. I’ve heard it said that front wheel weights can put the front suspension into too much tension at times.
